Matthew,

Forgive me. I tend to use terminology indiscriminately when they both approximately do similar things. You want to inquire about a SPECT imaging...dAt SCAN is actually the agent injected into veins that reveal dopamine function or measure. I also had intended to provide links for more info, so here is some essential reading imho....


National Parkinson Foundation explains the whole thing; what to expect during procedure; what exactly is measured, etc.

The MJFF site has good info too!

I read that the scan should have wide distribution soon, but then an article at MJFF says it is now available in only 14 centers. I think having a more biochemical based diagnosis would be worth the trek. All you can do is ask....

Best,

Laura
